Sorry for my last post-I've pasted too much

That's the right post:
Hi. I've occured another problem. After downloading one more time ayir.exe and copying it into the Automation Anywhere installation folder, every task doesn’t work. When I want to run it, task is starting to run but doesn’t execute any steps. Do I have to reinstall Automation Anywhere? After reinstallment of application, registraion key will be still active? Please answer.
